My life is so awful

I dont know why i did in the first place, i just did. I only cut a bit, not even deep. My beb (best friend) found out, i only cut a little. I havent in a while, my beb made me promise not to. I only did on my wrist once, people saw, i said it was my cat. Someone threatened to tell if i made her mad. I am terrified. I almost cut again because if she tells, my life is over. On top of that, i have to move from the house ive lived in since 07, the guy i like doesnt like me back, a girl was making fun of me (she knows) in front of him like oh she likes bad boys, my life is so awful. Please help me :((((
